as long as Netbeans does not let me specify the line ending style of newly created files and does not provide me with an option to remove trailing whitespace on save, it's just not usable for my purposes.

Where I work, we have a very strict policy concerning these two things - actually it was me to formulate that policy in the first place, because having strict line endings makes the codebase look ever so cleaner.

Having clean line endings really helps with applying patches.

Not having options to fix these two aspects is just unprofessional - no matter how good the rest of the editor might be.
